The United Kingdom (UK) has a concentrated HIV epidemic, with an estimated 101,200 people living with HIV in 2015. A decrease in diagnoses among men who have sex with men (MSM), the group most affected by HIV transmission, has recently been observed, and is probably due to increased frequency of testing (3 monthly) among those at greatest risk and rapid treatment for those testing positive.

Pre-exposure prophylaxis (PrEP) is an evidence based biomedical HIV prevention strategy which involves HIV negative individuals taking antiretroviral drugs to reduce probability of infection if exposed. The UK PROUD study found PrEP reduced HIV infection risk by 86% among MSM. PrEP is available on the NHS in Wales and Scotland. In October 2017, the IMPACT trial commenced in England, with PrEP being rolled out to 10,000 eligible people.

The project will explore and describe MSM and health professional perspectives on PrEP using qualitative interviews in three Northern cities (Liverpool, Manchester, Sheffield) and one city in the West Midlands (Birmingham) where PrEP is available through the IMPACT trial. Interviews with a purposive sample of participants (8-12 MSM and 4-8 health professionals per city) will focus on: PrEP awareness and sources of information including eligibility, compliance, drug interaction and online sourcing; impact of PrEP on HIV testing patterns, hepatitis C, sexual risk and other sexually transmitted infections; and on issues related to accessing PrEP and optimal service provision

The project is timely given the current IMPACT trial in England, with results informing policy, practice and professional training.

A commissioned article in Lancet Infectious Diseases on July 9, 2017 highlights some of the major issues and challenges facing us in the growing global epidemic of sexually transmitted infections (STI). Authors Prof Mabhus Unemo et al summarise the key issues as follows:

WHO estimated that nearly 1 million people become infected every day with any of four curable sexually transmitted infections (STIs): chlamydia, gonorrhoea, syphilis, and trichomoniasis. Despite their high global incidence, STIs remain a neglected area of research.

In this Commission, we have prioritised five areas that represent particular challenges in STI treatment and control.

Chlamydia remains the most commonly diagnosed bacterial STI in high-income countries despite widespread testing recommendations, sensitive and specific non-invasive testing techniques, and cheap effective therapy. We discuss the challenges for chlamydia control and evidence to support a shift from the current focus on infection-based screening to improved management of diagnosed cases and of chlamydial morbidity, such as pelvic inflammatory disease.

The emergence and spread of antimicrobial resistance in Neisseria gonorrhoeae is globally recognised. We review current and potential future control and treatment strategies, with a focus on novel antimicrobials.

Bacterial vaginosis is the most common vaginal disorder in women, but current treatments are associated with frequent recurrence. Recurrence after treatment might relate to evidence that suggests sexual transmission is integral to the pathogenesis of bacterial vaginosis, which has substantial implications for the development of effective management approaches.

Lastly, STIs in men who have sex with men have increased since the late 1990s. We discuss the contribution of new biomedical HIV prevention strategies and risk compensation.

Overall, this Commission aims to enhance the understanding of some of the key challenges facing the field of STIs, and outlines new approaches to improve the clinical management of STIs and public health.

The International AIDS Conference in Durban, South Africa, in July 2016, has renewed interest and momentum around HIV prevention. High and sustained HIV incidence rates—about 2 million people acquiring HIV every year for the past 5 years—highlight the need for new prevention technologies for populations at substantial risk of HIV.1 As many as 7000 new infections a week are occurring in the most vulnerable adolescent girls and young women in eastern and southern Africa.1 75% of young people in sub-Saharan Africa living with HIV are adolescent girls and young women age 15–24 years; AIDS is the leading cause of death for girls age 10–19 years in Africa.1 To date, prevention efforts have not had sufficient effect on risk of HIV in adolescent girls and young women.

Oral pre-exposure prophylaxis (PrEP)—the use of antiretroviral medications by HIV-negative people to avoid getting HIV—is a new biomedical intervention that has the potential to substantially reduce HIV acquisition in the people at greatest risk. Recent evidence suggests that PrEP was effective among several populations in reducing the risk of HIV infection by 70%.2 Less is known about the effectiveness of PrEP for young women,2 but the intervention could greatly increase the ability of adolescent girls and young women to protect themselves from HIV if they are able to access and use it effectively.

Applications are invited from researchers in various fields related to sexual health, HIV and other sexually transmitted viruses.

Sexually Transmitted Infections Research Foundation (STIRF) was set up to pump prime research projects relating to the epidemiology, pathophysiology, management, and health care delivery of sexually transmitted infections and HIV in the East and West Midland, the North East and North West Regions.

The primary aim is to provide initial funding to allow promising projects from young researchers to obtain preliminary results as a prelude to acquire further funds from larger funding bodies.

We invite applications from researchers in the above regions on projects relating to sexually transmitted diseases and HIV. All projects will be initially screened by the Scientific Committee of STIRF and those considered suitable will be sent for peer review by experts in the field.

The following fields of research will be considered in relation to STIs and HIV

Epidemiology of HIV and other sexually transmitted diseases

Research on HPV and other sexually transmissible malignancies

Health care delivery including views of clients

Issues relating to deprived or marginalised communities.

Pathophysiology of diseases and syndromes

Inter-relationship between diseases

Treatment modalities

Complications of treatment and co-morbidities

Applications should not exceed £50,000 in the first year. Depending on satisfactory reports a further £25,000 may be available for the second year. Joint funding with other grant giving bodies will be considered.

Somalis are absent from much of the official statistics largely because ‘Somali’ is rarely recognised as a distinct ethnic category. Therefore, when decisions are being made in relation to addressing the needs of recently arrived refugees the needs of those who originate from Somalia may be neglected.

Somalis are known to have a high level of need but low uptake of health care services. This included sexual health.

Earlier STIRF funded a project which looked at issues and problems relating to access for sexual health services. The project is now completed and is presented in a meeting held on:

Daily HIV medicine taken by men who have sex with men (MSM) reduces risk of HIV infection by 86% as was reported by Molina J-M, and colleagues in the ANRS Ipergay trial at the Conference on Retroviruses and Opportunistic Infections held in Seattle, USA in 2015 (23LB.).

Molina et al reported the final results of a three year study which randomised MSM who were negative for HIV to either take daily HIV prophylaxis with two anti-retroviral drugs in a single tablet immediately or deferred for 1 year.

The study showed that those taking the drugs on a daily basis have a 86% reduction in the risk of being infected by HIV than MSM not taking the drug (p=0.0001). The trial was stopped in October of 2014 and all participants in the deferred group were offered pre-exposure prophylaxis (PrEP)

The science is now clear: oral pre-exposure prophylaxis (PrEP) with a coformulation of tenofovir disoproxil fumarate and emtricitabine (Truvada) significantly reduces the risk of HIV infection among individuals at high risk of HIV infection.

The news that PrEP has shown consistent efficacy among those who take it as prescribed should be a cause for celebration, and galvanise action to ensure access to PrEP for those who could benefit the most. But almost 3 years since the US Food and Drug Administration approved tenofovir–emtricitabine for PrEP little is being done on implementation.

A large international study (INSIGHT START) published in the New England Journal of Medicine has found that starting antiretroviral therapy immediately after human immunodeficiency virus (HIV) diagnosis rather than waiting until a patient’s CD4+ count has declined is of considerable benefit.

The results of the study were also released at the International AIDS Society conference in Vancouver, Canada, on 20 July.

Currently most authorities strongly recommend starting anti-HIV once CD4+ count drops to below 350 cells per cubic millimetre. Until the INSIGHT START study there was no randomized trials showing the benefits and risks of initiating antiretroviral therapy in patients with asymptomatic HIV infection who have a CD4+ count of more than 350 .

After a mean follow up of 3 years the study found that 42 patients in the immediate-initiation group died, as compared with 96 patients in the deferred-initiation group (95% confidence interval, 0.30 to 0.62; P<0.001). Reduction in deaths were largely from tuberculosis, Kaposi’s sarcoma, and malignant lymphomas – conditions that can occur in HIV-infected individuals with only moderately damaged immune systems.

Currently the WHO requires all patients with HIV to be treated CD4+ of 500 or less. WHO may need to extend that to treating anyone at diagnosis. This would not only benefit the individual but by reducing viral shedding in body secretions reduce transmission and hence have a public health benefit. Moreover some of the costs of starting early would be offset by not needing to perform repeated CD4+ counts.

On May 8 2014 the UK Court of Appeal dismissed the appeal of David Golding against a 14 month prison sentence for transmitting herpes to his partner.

An Editorial in the BMJ by Emily Clarke an colleagues highlights the numerous and complicated issues that arise from this verdict including:

what constitutes grievous bodily harm,

how you determine that sexual transmission has occurred,

how serious is herpes infection, and

what this judgement means both for health care workers who advise and inform patients on the risks of transmission and on the infected individual and their duty of informing all partners of potential risk of transmitting an infection even during asymptomatic shedding.

The Editorial correctly highlights the dangers of criminalizing sexually transmitted infections and the various problems that arise from this judgement which was based on a law passed 170 years ago addressing totally unrelated issues and at a time when STI’s were not understood as they are today.

This is part of a series of articles on HIV and sex workers published by The Lancet and freely available.

In this article Michelle Decker et al reviewed evidence from more than 800 studies and reported on the burden and HIV implications of human rights violations against sex workers.

Abuses of human rights are perpetrated by both state and non-state actors. Such violations directly and indirectly increase HIV susceptibility, and undermine effective HIV-prevention and intervention efforts.
